From a news story about the investigation:

The video was taken by an employee of Compassion Over Killing who was hired by Cal-Cruz Hatchery in January 2009 to perform maintenance work. He worked at the hatchery for only a few weeks, secretly documenting the mistreatment of ducklings with a hidden video camera, said Erica Meier of Compassion Over Killing.
